How to create first Android Studio Project.
The quickest way to get to know Android Studio is to use it to develop an android app.
start with a variation on the "Hello, World" app: a little mobile app that
displays a "Welcome to Android App" message.
In the steps that follow, you'll start a new Android Studio project and get to know the main window, including the editor window that you'll use to code the app in Part 2.
Create New Project
From our setup so far, you should still have Android Studio running with the Welcome to Android Studio dialog box. From here, click Start a new Android Studio project. Android Studio will respond with the Create New Project dialog box shown in Figure 2.
Enter W2AA (Welcome to Android App) as the application name and javajeff.ca as the company domain name. On my desktop, I observed C:\Users\JEFF\AndroidStudioProjects\W2AA as the project location. Click Next to select your target devices as shown in figure 3.
Android Studio lets you select form factors, or categories of target devices, for every app you create. I kept the default setting. Click Next, and you will be given the opportunity to choose a template for your app's main activity. For now we'll stick with Empty Activity. Select this template (if necessary) and click Next as shown in figure 4.
Next you'll customize the activity:
Enter "Welcome to Android App" as the activity name and main as the layout name, and click Next to complete this step as shown in figure 5.
The first time you use Android Studio, you'll discover that it has to download some files, which is used to build responsive user interfaces:
Adhuc quaerendum est ne, vis ut harum tantas noluisse, id suas iisque mei. Nec te inani ponderum vulputate, facilisi expetenda has et. Iudico dictas scriptorem an vim, ei alia mentitum est, ne has voluptua praesent.
Sumo euismod dissentiunt ne sit, ad eos iudico qualisque adversarium, tota falli et mei. Esse euismod ad, nec et tantas semper delicatissimi.
Duis sed odio sit amet nibh vulputate cursus a sit amet mauris. Morbi accumsan ipsum velit. Duis sed odio sit amet nibh vulputate cursus a sit amet mauris
Investigationes demonstraverunt lectores legere me lius quod ii legunt saepius. Claritas est etiam processus dynamicus, qui sequitur mutationem consuetudium lectorum.
Typi non habent claritatem insitam; est usus legentis in iis qui facit eorum claritatem.
